When is Gibrat's Law a Law?
() and Niklas Elert
Abstract: The purpose of this paper is to investigate if the
industry context matters for whether Gibrat's law is rejected or not using
a dataset that consists of all limited firms in 5-digit NACE-industries in
Sweden during 1998-2004. The results reject Gibrat's law on an aggregate
level, since small firms grow faster than large firms. However, Gibrat's
law is confirmed about as often as it is rejected when industry-specific
regressions are estimated. It is also found that the industry context -
e.g., minimum efficient scale, market concentration rate, and number of
young firms in the industry - matters for whether Gibrat's law is rejected
